Hello fellow parents, I am an American, living in London. I have twins that will be 4 in May. daughter is very laid back, does as she is told most of the time, calm, happy entertaining herself. What I would consider average for a child her age. Her twin brother is the exact opposite. From day 1 here are characteristics about him that we have noticed: Fidgits non stop (even in his sleep!) He.does.not.stop.moving Loud (has no awareness of tone or volume) Impulsive Tantrums (not what I would call normal 3/4 year old tantrums Does not listen (we think this is mainly linked to needing tubes in his ears - which is taking MONTHS to sort on the NHS here in the UK) Has a hard time following simple instructions Gets frustrated easily - putting on shoes, clothes, etc despite being capable Attention seeking/jealous when twin sister gets attention and he feels need to sabotage Blurts out (out of nowhere? He can be watching TV and then feel the need to scream out a word totally unrelated? IT scares me to death when he does this! I literally jump out of my skin) Has to be told over and over not to do something. It really seems like he just cannot help himself to NOT do something that he is told to stop doing. Cannot wait his turn Super demanding from the moment he wakes up No apathy for other's emotions. ie., if his sister or I am upset/crying - he smiles. No sense of danger (he was walking at 10 months old and had broken his arm before 18 months old) He is always climbing, jumping off things, etc. Last December we flew to the states to visit my parents for the month. My mother commented on how she wouldn't be surprised if DS was on the Autistic Spectrum. Now, if anything I would suspect ADHD but Autism never crossed my mind. DS is very social for one - which is not something I would characterize with Autism. I suppose it would be nice to hear from other parents with either an ADHD child or an Autistic child to see if any of my DS's symptoms match those of your child. I put my own career on hold to be a mother to my twins and I find myself wishing things were different. I think about how easy life would have been if I only had my daughter. I envy my friends who have one child - who can take their 4 year old child out in public without the fear of an outbreak, spoiled tantrum and the worry of a child hurting themselves because they aren't listening. I'm in constant stress and worry over my DS. He seems to disrupt the entire day and is a whirlwind of emotional wreckage for our family. The strain of his hyperactivity is affecting both me and my husband. We are at our wits ends. I have lost so much faith in the NHS here in the UK. DS has had hearing issues since last Oct. Waiting times for appointments in months and despite the doctors saying his last hearing test showing his hearing has been compromised - nothing has been done. We were given nose spray and a follow up appointment 4 1/2 months later (which is this Saturday). I hate to think that if I bring this separate behavioral issue up to our Dr how long it will actually take for someone to listen to me. I feel so frustrated.
